history
Project history and usage
icoutils is a GPL command-line toolkit for extracting, converting, creating, and scripting Microsoft Windows icon and cursor resources on POSIX systems.
Project history
The icoutils homepage identifies Oskar Liljeblad as the original creator and records copyright beginning in 1998. The project lives on NonGNU/Savannah, with Savannah's cgit repository treated by the homepage as the authoritative source when mirrors differ.
Its core tools cover different layers of Windows icon handling: icotool converts .ico and .cur files to and from PNG images, wrestool extracts icons and cursors from PE and NE executables and libraries, and extresso automates extraction/conversion through resource scripts.
Adoption history
The Savannah release directory shows packaged source releases from 0.26.0 in 2005 through 0.32.3 in 2018. The homepage also points to Debian package pages, and the input metadata lists packaging across Homebrew, Debian, Ubuntu, Fedora, Arch, Alpine, MacPorts, Nix, and openSUSE.
Homebrew packages icoutils with libpng, exposing it to macOS and Linux users who need Windows resource conversion without a Windows development environment.
How it is used
The package is used when icons or cursor images are locked inside Windows executable formats or when PNG assets need to be assembled into .ico/.cur files for cross-platform software distribution.
The homepage states that icoutils was designed for modern POSIX-compatible systems such as Linux, making it useful in build scripts, packaging pipelines, and asset-conversion jobs.
Why package nerds care
icoutils is the sort of small format utility that package repositories quietly depend on: it is not glamorous, but it solves an annoying binary-resource problem with composable commands.
Its significance is strongest in cross-platform packaging, where Unix build systems need to inspect or generate Windows icon resources without bringing in a GUI resource editor.
